1. In combination:

  • a laser diode bar having a plurality of emitter regions having output facets,a microlens comprising an optical fiber having an axis oriented substantially perpendicular to and positioned in the emission path of radiation from said emitter regions to be optically coupled thereto and spaced therefrom by a distance of approximately one focal length of said microlens,a plurality of optical fibers equal to the number of emitter regions of said laser diode bar, and oriented on axis with respect to said microlens such that radiation from said individual ones of said emitter regions is optically coupled into individual ones of said plurality of optical fibers.
